Memento MCP server

Memento is a small helper that gives your AI coding assistant a memory. It remembers facts, decisions, patterns, and past problems about your project, stored safely on your own computer. It is handy for anyone who uses an AI coding tool and is tired of explaining the same project details in every new chat.

What this MCP server does

You install Memento once and connect it to your AI coding tool. From then on, when you ask your AI something, the AI can quietly check the memory store for related notes. If you tell the AI to remember something, it saves that note for later. The memory lives in a small database file on your computer, and you can browse it in a local web page. You can also share selected notes with your team through your project's normal file sharing.

What you can do with it

• Remember project decisions so you do not re-explain them
• Save known pitfalls and debugging notes for later
• Store coding patterns and conventions your project follows
• Import existing notes from files like CLAUDE.md or AGENTS.md
• Search past session summaries to see what you were doing
• Browse and inspect everything the AI has remembered in a local web page
• Share chosen notes with teammates through your project files

Try asking your AI

• “Remember that we chose Postgres over MySQL for this project because of the JSON support.”
• “What did we decide about the login flow last week?”
• “Have we hit this error before? Check your memory.”
• “Summarize what we worked on in this session and save it.”

What it gives back to you

You get answers in plain chat, drawn from what was saved before. When the AI saves something, it confirms the note was stored. When you search, you get a short list of matching notes with a snippet. In the local web page you can see full lists of memories, sessions, and projects.
